@Kal_Lam I did so, and the changes stipulated above were made in the XLS form, i saved t and replace with the existing one in the server, unfortunately, the same error pops up!!
What should i do?
or else, i may share my project with you @Kal_Lam so you can see yourself!!
@lawrenceluke, OK this issue is something different. Maybe you will need to do the following to solve this:
Download your project as XLSForm.
Search for np3fd79 under the survey tab and the choices tab. If you have used it under the survey tab, you will also need to define the values under the choices tab.
Maybe validating your XLSForm through his online validator should also help you identify syntax issues if present within your XLSForm.
